Patented Jan. 2, 1934 1,941,530 ELEVATING AND DUMPING DEVICE Arthur R. Beck and John S. Warren,

Chicago, Ill.

Application March 20, 1931. Serial No. 524,007

1 Claim.

This invention relates to an elevating and dumping apparatus which is particularly adapted to elevate and discharge the contents of large portable receptacles such as a barrel, and is par- 5' ticularly adaptable for meat packing plants where it is desired to raise and invert a barrel of meat or the like, usually weighing several hundred pounds, to discharge the contents into a meat grinding or other machine. My device may be conveniently and efliciently employed for '6; machine or upon a work table.

A further object of my invention is the provision of a novel carrier and guide means therefor which may be economically manufactured and installed and which may be efficiently operated either by hand power of electrical or compressed air hoists, said apparatus effecting a considerable saving in labor and time which is ordinarily required in removing meat or other products from barrels, trucks or other receptacles.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawing.

This invention (in a preferred form) is illustrated in the drawing and hereinafter more fully described.

On the drawing:

Fig. 1 is a side elevation view of my device showing the carrier in position on the guide rail and. showing in dotted lines the position of said carrier and a barrel therein in discharging position.

Fig. 2 is a cross sectional view taken on line 11-11 of Fig. 1.

Fig. 3 is a side elevation taken on line IIIIII of Fig. 1 showing the means of mounting the carrier on the guide rails.

As shown on the drawing:

The reference numerals 10 and 10' indicate guide rails of sturdy construction which are bent to conform to a large letter 2 at points a short distance above the open end of a machine or table into which the contents of the receptacles or trucks are to be discharged. The upper end ofthe rails 10 and 10' are rigidly secured in flanges 11 (only one of which is shown) which are securely bolted to the ceiling or other stationary mounting means. The floor ends of the rails 10 and 10 are bent at right angles and to form a loop. Leg screws 12 and 12 having washers 13 and 13' are threaded into the floor to securely hold said guide rails 10 and 10' in rigid position.

A connecting bar 17 passes through the lower ends of mounting plates 14 and 14' and has outwardly projecting threaded ends for engagement of nuts to secure said mounting plates 14 and 14 in rigid position.

It is to be understood that While we have described the mounting plates and cross bar as separate parts, these may be economically and practically formed of one integral member by stamping the same into U-shape.

A bail 18, which is of sufiicient size to swing well above the top of the barrel or other receptacle, has its respective looped ends pivoted on the outside of mounting plates 14 and 14 by means of bolts 19 and. 19 which pass through and are secured in the mounting plates 14 and 14 near the lower end thereof.

The bail 18 is preferably looped at its extreme upper center to provide convenient attaching means for a flexible cable 20 which passes upwardly and over a pulley 21 which is rotatably mounted in bracket 22 secured in the ceiling or other stationary mounting member. The end of the cable (not shown) is attached to a compressed air or electric hoist which is manually operated to raise said elevator to any desired position.

So that the barrel or other receptacle may be securely held in the carrier, to prevent the same from slipping out therefrom when it is inverted, we provide retaining brackets 22 and 22' which are slidably mounted in opposed relation to each other on the inside of the mounting plates 14 and 14' respectively. Bolts 23 and 23 pass through apertures in the brackets 22 and 22' respectively and through longitudinal slots 24 in mounting plates 14 and 14', and adjustably secure said brackets to said mounting plates 14 and 14' so that such brackets may be secured to rigidly hold receptacles of various sizes. The elevator containing a receptacle as above described is slidably movable between guide rails 10 and 10', the guiding means comprising a plurality of swivel eyelets 25 and 25, preferably two on each side, which are swivelly mounted in said mounting plates 14 and 14' respectively. The eyelets 25 and 25' are pivotally mounted in mounting plates 14 and 14' at a point substantially intermediate the center and ends of each mounting plate.

It will be apparent from the foregoing description and the accompanying drawing that after the receptacle is placed in the carrier and secured therein, the pull on cable 19 will cause said carrier to be elevated and inverted to the position shown in dotted lines in Fig. 1. In this position the contents of the receptacle will be gradually discharged into the machine 2'7. Thereafter the carrier and receptacle therein may be conveniently returned to its lowermost loading position.

We are aware that many changes may be made and numerous details of the invention and construction thereof may be varied through a wide range without departing from the principles of this invention, and we therefore do not desire to limit the patent granted thereon otherwise than necessitated by the prior art.

What is claimed is:

In an elevating device a pair of stationary guide tracks of substantially Z shape; a carrier movable between said guide tracks comprising a rectangular frame and a pair of laterally extending ribs attaches thereto; guide members on said carrier movably engaging said guide tracks said guide members comprising swivel eyelets to permit slidable movement along said tracks; a bail pivoted on one side of said carrier, and manually operable hoisting means adapted to elevate said carrier to inverted position between the angles of said guide tracks.
